<h1>Tutorial &minus; Introduction</h1>

<p>This tutorial is intended to introduce you to the CodeIgniter framework and the basic principles of MVC architecture. It will show you how a basic CodeIgniter application is constructed in step-by-step fashion.</p> 

<p>In this tutorial, you will be creating a <strong>basic news application</strong>. You will begin by writing the code that can load static pages. Next, you will create a news section that reads news items from a database. Finally, you'll add a form to create news items in the database.</p>

<ul>
<li>Model-View-Controller basics</li>
<li>Routing basics</li>
<li>Form validation</li>
<li>Performing basic database queries using &quot;Active Record&quot;</li>
</ul>
